Product Description

Probelle Nail Hardener FORMULA 1
Unique formula designed to cure, repair, and restore damaged nails. Formula 1 prevents and corrects thin nails that are breaking and cracking by forming a protective barrier on the nail. Using Formula 1 on a daily basis will restore nails to a healthy state.

Nails will take 2-3 weeks to reestablish to a healthy state and will continue to grow strong natural nails. Formula 1 can be applied as a base coat and as a top coat for better performance.

Apply a thin coat daily for several days to stop peeling, cracked, and split nails. Use as a base coat with regular manicure once the nails becomes healthier and stronger.  After 2-4 weeks, we recommend treatment to be continued with Nail Maintenance (Formula 2).

  1. Works the Best on Natural Nails

    Posted by Kimberly C. on 18th Sep 2018

    This product is excellent! Worth every cent! If used as directed, this hardener strengthens and grows your nails before you know it. I no longer have short, weak, thin, peeling nails. I appreciate that my nails after using Formula 1 look so attractive & feminine. The hardener doesn’t peel off even when I wash dishes without gloves. I am moving to Formula 2 to see if my nails remain strong and long.

  5. Big Recommendation!

    Posted by Nicole on 23rd Feb 2015

    I normally have either acrylic or gel nails but occasionally like to take them off and let my natural nails “breath” for a few months. After removing the fake nails, my natural nails are brittle, soft and flaky. This time around, I started to use Probelle’s Touch n’ Grow and Touch n’ Grow Plus to bring my nails back to life. I applied a thin coat of Touch n’ Grow on a daily basis and within 2 or 3 weeks, my nails started to grow in strong and healthy. They’ve grown just wonderfully!! I have now decided that I will be staying with my natural nails since they have grown so nicely! RECOMMEND!!

  6. Best product ever

    Posted by Debbie on 3rd Dec 2014

    If you follow the directions for this product you will get the results you want. I have tried many products for nail repair and growth none worked until I found this product. In my opinion BEST PRODUCT EVER. My nails use to split down the middle and peel after using this product the problem stopped to my surprise. Before finding pro belle I had artificial nails now I have my own nails. No more artificial nails for me. Best product ever, I wish I would have found pro belle sooner.

  7. need to add how awesome probelle is

    Posted by stephanie on 26th Aug 2014

    ... as I said what a nail freak I am trying so many different things to get my nails to grow I'm 41 my nails would grow but only last the longest 3-4 weeks when 1 would break they all started like a domino affect . They were long when I was pregnant only because of the vitamins. I work in a paper factory so that really dries my hands and cuticles im always putting lotion and oil on my hands and fingers. . I finally have stopped searching for a nail treatment. this stuff is a miracle you won't regret buying Probelle. I've thrown away all my other nail strengtheners. I also take a multi vitamin and biotin. Thank you PROBELLE your a life saver :-D

    This stuff is awesome I LOVE the way it goes on.. my nails haven't looked better. I've tried so many products I'm a nail freak. There's a few times I smacked my nails and thought for sure I broke it and they were fine. I so "RECOMMEND" this product (2 THUMBS UP)
